> Europe where there are 5-6 completely different colours used, one for each note. I quite like that and never really understood why US bills are only green. If I look for 50€ in my wallet, I’m going to skip over the blues and greens and essentially directly pick the right orang-y one. I’ve also never seen anyone suspicious of 50€, people sometimes look funny if they see 100€, but even that happens rarely.
